Before plunging her silicone-strapped dildo into her submissive partner's tight ass, the dominant woman insists on a thorough warm-up. She uses her fingers and a small vibrator to relax the clenched muscles, watching as her partner's asshole puckers and opens with each touch. She lubes up the strapon, teasing her partner's entrance with the tip, before finally sliding it in, inch by inch, until it's fully seated.
